One of my students has successfully installed Alice 3.1 the current build on her computer, she also has Java 8 with netbeans installed. I can usually fix problems with Alice for my students (normally they forget to install Java etc.. ) but this one has me puzzled.

She is in the middle of adding objects to a scene and Alice unexpectedly (seems to be randomly) shuts down. It just does what I call " a graceful close " - no error messages nothing.

The program opens up fine and I too have tried from scratch adding objects sometimes it is on the first object sometimes the third, sometimes later as she is moving an object.
